| Abstract: | Photo-and thermo-stable luminescent beads composed of Eu(hfa)(3)(TPPO)(2) (hfa: hexafluoroacetylacetonate, TPPO: triphenylphosphine oxide) and PMMA (polymethylmethacryrate), Eu(hfa)(3)(TPPO)(2)-beads, have been reported for improvement of energy conversion efficiency on silicon solar cell. The photophysical properties of Eu(hfa)(3)(TPPO)(2) and compared Eu(tta)(3)(TPPO)(2) (tta: trifluoromethyl- thienylacetylacetonate) are characterized by the emission quantum yield, the emission lifetime, the radiative and the non-radiative rate constants. Photo-and thermo-stability of the beads with Eu(III) complexes in EVA (Ethylene Vinyl Acetate) are estimated under UV irradiation (Xenon lamp: 60 W/m(2)) and highly temperature (120 degrees C). The stability of the Eu(hfa)(3)(TPPO)(2)-beads for industrial application was calculated to be ten years under air condition. Energy conversion efficiency of silicon solar cells attached EVA films with Eu(hfa)(3)(TPPO)(2)-beads increased approximately 2%(10% -> 10.2%) compared with EVA films contained with UV absorber. Photo-and thermo-stable Eu(hfa)(3)(TPPO)(2)-beads for silicon solar cells are demonstrated for the first time. |
